Onychia without granuloma

• Onychia is an inflammation of the matrix (surrounding tissue) of the nail with formation of pus and shedding of the nail. Onychia results from the introduction of microscopic pathogens through small wounds.

• Onychocryptosis, commonly known as "ingrown nails" (unguis incarnatus), can affect both the fingers and the toes. In this condition, the nail cuts into one or both sides of the nail bed. The relative rareity of these infections in fingers suggests that pressure from the ground against the toe is a prime factor. The movements involved in walking, or other disturbances, can contribute to the problem. Mild onychocryptosis, particularly in the absence of infection, can be treated by trimming and rounding the nail. More advanced cases, which usually become infected, are treated by surgically excising the ingrowing portion of the nail down to its bony origin and cauterizing the matrix, sometimes called the 'root', to prevent recurrences. This surgery is called matricectomy . The best results are achieved by cauterizing the matrix with phenol. Another method, which is much less effective, is excision of the matrix, sometimes called a 'cold steel procedure'.
• Onychodystrophy is a deformation of the nails that can result from cancer chemotherapy which includes bleomycin, hydroxyurea, or 5-fluorouracil.

Grphyphotic nail with mycotic changes

• Onychogryposis, also called "ram's-horn nail", is a thickening and increase in curvature of the nail. It is usually the result of injury to the matrix. It may be partially hereditary and can also occur as a result of long-term neglect. It is most commonly seen in the great toe but may be seen in other toes as well as the fingernails. An affected nail has many grooves and ridges, is brownish in color, and grows more quickly on one side than on the other. The thick curved nail is difficult to cut, and often remains untrimmed, exacerbating the problem.

• Onycholysis is a loosening of the exposed portion of the nail from the nail bed, usually beginning at the free edge and continuing to the lunula . It is frequently associated with an internal disorder, trauma, infection, nail fungi, allergy to nail enhancement products, or side effects of drugs.
• Onychomadesis is the separation and falling off of a nail from the nail bed. Common causes include localized infection, minor injury to the matrix bed, or severe systemic illness. It is sometimes a side effect of chemotherapy or x-ray treatments for cancerFor other meanings of Cancer: see Cancer (disambiguation . apoptosis; cancer cells, however, avoid apoptosis. Cancer is a group of related diseases characterized by uncontrolled cell division. Currently, it is believed that cancers arise from both genetic. A new nail plate will form once the cause of the disease is removed.
• Onychomycosis , also known as tinea unguium, is a contagious infection of the nail caused by the same fungal organisms which cause ringwormRingworms can also refer to fans of the Japanese Ring series of horror novels and films, as well as the US remake. Ringworm also known as Tinea is a contagious skin fungus that manifests initially as a flat hairless patch on the skin which later expands t of the skin. It can result in discoloration, thickening, chalkiness, or crumbling of the nails and is best treated by powerful oral medications, although it sometimes responds to a combination of topical medication and periodic filing of the nail surface.
• Onychophosis is a growth of horny epitheliumIn zootomy, epithelium is a tissue composed of epithelial cells. Such tissue tends to surround parts of the body, somewhat like a cell membrane. It is also used to form glands. The epithelium is usually the layer of cells 'closer' to the outside world. in the nail.
• Onychoptosis is the periodic sheddng of one or more nails, in whole or part. This condition may follow certain diseases such as syphilisSyphilis (historically called lues is a sexually transmitted disease (STD) that is caused by a spirochaete bacterium, Treponema pallidum''. Syphilis has many alternate names, such as: Miss Siff, the Pox, and has been given many national attributions, e., or can result from feverFever also known as pyrexia is a medical symptom which describes an increase in temperature to levels which are above normal (37 degrees Celsius 98. 6 degrees Fahrenheit). An adaptive mechanism, fever is the body's reaction to pathogens; it attempts to ki, traumaIn medicine, a trauma patient has suffered serious and life-threatening physical injury resulting in secondary complications such as shock, respiratory failure and death. Trauma patients require specialized care including surgery and often blood transfusi, systemic upsets or adverse reaction to drugs.
• Paronychia is a bacterial or fungal infection where the nail and skin meet. Pus is usually present, along with gradual thickening and browning discoloration of the nail plate. Paronychia around the entire nail is sometimes referred to as runaround paronychia. Chronic paronychia is most often caused by a yeast infection of the soft tissues around the nail but can also be traced to a bacterial infection. Individuals who work with their hands in water, such as health care workers and food processors, are quite prone to this type of infection.
• Kolionychia is when the nail curves upwards due to an iron deficiencyIron deficiency (plant disorder) Iron deficiency (medicine)..

• Subungual hematoma occurs when trauma to the nail results in a collection of blood, or hematoma, under the nail. It may result from an acute injury or from repeated minor trauma such as running in undersized shoes. Acute subungual hematomas are quite painful, and usually are treated by releasing the blood via a hole drilled in the nail.
